The Kincrome Replacement Diaphragm Pump Heads offer a cost effective and time saving solution to refurbish the head on your Kincrome 12V sprayer or diaphragm pump. This replacement pump head is a direct bolt-on replacement for K16103. The Kincrome replacement diaphragm pump heads include components that are designed to reduce wear and keep working, like a Honeywell MICRO SWITCH™, a Santoprene™ diaphragm and a chemical-resistant fiberglass-reinforced polypropylene pump manifold. The innovative smooth valve design provides faster primes. It also has our unique pressure switch, designed to slowly cycle the pump to reduce switch and motor wear. Kincrome Sprayer pumps are all compatible with Roundup® agricultural herbicide.
